Abstract
Endoscopic cricopharyngeal myotomy (ECPM) is a safe and minimally invasive technique that is used to treat patients whose esophageal inlet fails to open because of specific diseases, such as Wallenberg's syndrome and neuromuscular diseases. The present study described the performance of a new, safe and simple ECPM using a curved rigid laryngoscope, which is used for endoscopic laryngopharyngeal surgery for patients with dysphagia due to pharyngeal residue after swallowing. The patient was an 80‑year‑old woman with laryngeal palsy caused by lower cranial nerve palsy after cranial base schwannoma surgery. ECPM was performed with a curved rigid laryngoscope. The postoperative course was good; postoperative rehabilitation eliminated the residue after swallowing a thickened solution and mealtimes were shorter than before surgery. This procedure allows the hypopharynx to be widely expanded and it is possible to develop a wider surgical field than when using a direct laryngoscope. In addition, this procedure appears to be relatively easy to perform if the surgeon is familiar with the curved rigid laryngoscope technique.
